Abstract

Es wird ein Sensorelement eines Gassensors beschrieben, das der bestimmung der Konzentration mindestens eines Bestandteils eines Gasgemischs, insbesondere in Abgasen von Verbrennungsmotoren dient. Es beinhaltet mindestens zwei Elektroden (22, 23), die in einem in direkten Kontakt mit dem Gasgemisch stehenden inneren Gasraum (15) angeordnet sind, wobei die eine Elektrode (22) ein erstes Material und die zweite Elektrode (23) ein zweites Material enthält. Der innere Gasraum (15) enthält ein physikalisch und/oder chemisch wirkendes Mittel (34, 36, 38, 39) zur Vermeidung einer Metalldiffusion zwischen den Elektroden (22, 23).
